| Popis: | In this paper, we present a complete transrating architecture for H.264/AVC high-definition video bitstreams. Based on frequency-selective filtering, this architecture has a minimized complexity and is drift-error-free for intra-coded pictures. Moreover, both Video Quality Metric (VQM) experiments and subjective analysis show that the algorithm gives satisfactory results in terms of visual quality. Our solution introduces blurring only compared to conventional requantization transrating, which also introduces other artifacts as distortion. We propose an easy and efficient bitrate estimation model controlled by transrating parameters. |
